✨ POE::Component::Resolver::Sidecar ✨ 💅

okay bestie, so this is a page from the User Contributed Perl Documentation manual, and it's literally called POE::C...Sidecar(3pm) because the terminal was like "girl, that name is too long" and truncated it. we move.

NAME 🎀

POE::Component::Resolver::Sidecar — delegating to a subprocess so it can call getaddrinfo() for you 🫶

VERSION 🌸

version 0.921 ✨ (she's got a version number and she's not afraid to use it)

SYNOPSIS 🦋

Used internally by POE::Component::Resolver.

that's it. that's the whole synopsis. it's giving "I'm the backstage crew, not the main character" energy and honestly? iconic. 👑

DESCRIPTION 💖

so here's the tea, bestie: POE::Component::Resolver spins up subprocesses whose whole job is to call getaddrinfo(), and the reason is everything — because otherwise your main program would just be sitting there blocking the whole time, like a friend who says "omw" and then doesn't move for twenty minutes. 😭 no cap.

the actual code that does the getaddrinfo() calling lives in this module, all abstracted out, specifically so it can be run as a separate executable program. why do we care? because it means you don't have to fork your entire main process just to do one little getaddrinfo(), which would blow up your memory footprint for literally no reason. it's giving ✨efficiency✨.

and fr fr, this is a strong, useful pattern — other POE::Components have been doing this before us. POE::Quickie does it in a generic way. POE::Component::SimpleDBI and POE::Component::EasyDBI do it too, so that their DBI subprocesses stay relatively lightweight. slay. 💅

main 🧚

the main code's whole vibe is: read POE::Component::Resolver requests from STDIN, and write getaddrinfo() responses to STDOUT. in through the front door, out through the back, no drama. 🌈

and that's the whole page, bestie!! this beauty shipped with perl v5.26.1 and got its date stamped 2018-04-08, which is lowkey ancient in internet years but she still ate. 🫶 stay unblocked, call your getaddrinfo() in a subprocess, and never fork your whole self for one tiny lookup. periodt. 💅✨
